研究目的
To investigate the luminescence properties and laser potential of lithium lanthanum borated glasses doped with Nd3+ (LiLaBNd) for use as a laser medium in green emitting laser devices.
研究成果
The study demonstrates that lithium lanthanum borate glasses doped with Nd3+ have potential as laser media in green emitting solid-state lasers. The optimum concentration of Nd2O3 was found to be 0.50 mol%, which provides the maximum emission intensity. The glasses exhibit favorable radiative parameters for laser applications.
研究不足
The study is limited to the synthesis and characterization of lithium lanthanum borate glasses doped with Nd3+. The practical application in laser devices requires further optimization and testing under operational conditions.
